I cross-posted this thread from the HTPC sub-forum. I made a thread 3 days ago and over 100 views with no responses(guess they're stumped too). I figure the fellow gamers of this sub-forum would have an idea.
My specs first I guess for my media PC
Integrated Radeon HD 7660D
25TB various size drives
Using AMD high Definition Audio Device through HDMI (Realtek audio disabled in BIOS)
Connected using HDMI to Denon AVR790
Windows 8 64bit
XBMC Frodo 12.1
In XBMC I get full digital audio. DTS-MA, DD-HD, all the audio works flawless. Its set to WASABI.
In metro Netflix I only get PLII and same with all of my games (steam or otherwise). If I set windows to 5.1 under playback/configure in windows, all I get is the subwoofer and XBMC/Netflix switches the AVR to Multichannel. I am stumped.
